Description

Technical Field

[0001] This disclosure relates to the field of glass fiber winding technology, and more specifically, to a thermosetting glass fiber cloth winding and curing apparatus. Background Technology

[0002] With the development of modern industry, especially in aerospace, automobile manufacturing, and wind power generation, the demand for high-performance composite materials is increasing. Thermosetting fiberglass cloth, as an important reinforcing material, occupies a significant position in many applications due to its excellent mechanical properties and low cost. However, traditional fiberglass cloth winding and curing processes have many shortcomings, such as low production efficiency, high energy consumption, and unstable product quality. These problems seriously restrict the further development of the industry.

[0003] Currently, the existing traditional glass fiber cloth winding and curing process has the following shortcomings: (1) Inefficient heating method: Traditional processes usually use a single external heating method, which leads to uneven heat transfer, long curing time, and difficulty in ensuring product quality consistency. (2) Serious energy waste: A large amount of waste heat generated during the curing process is often directly discharged into the environment without being effectively recycled, which not only increases production costs but also has a negative impact on the environment. (3) Lack of intelligent control: Most existing control systems are based on simple open-loop control or local feedback mechanisms, which cannot achieve full-process automation and intelligent management, and are difficult to meet the requirements of modern manufacturing industry for efficient and precise production.

[0015] Through the above technical solution, with the establishment of a working chamber and a heating chamber, the winding equipment can first wind the fiberglass cloth output from the resin impregnation system in the working chamber. After completing the winding, the winding equipment can move from the working chamber to the heating chamber through the first movable door, and use the heating and curing system in the heating chamber to heat and cure the fiberglass cloth on the mandrel. Meanwhile, the working chamber can be used for the next winding equipment to perform a new round of winding. In other words, the separation design of the working chamber and the heating chamber allows the winding and curing processes to be carried out in parallel in two independent spaces. That is, when winding equipment A is curing in the heating chamber, winding equipment B can perform a new winding operation in the working chamber. This alternating operation mode can achieve continuous production, reduce equipment waiting time, and further improve equipment utilization and production efficiency.

[0016] Furthermore, through the waste heat utilization system, whose input end is connected to the heating chamber and whose output end is connected to the interior of the mandrel, the waste heat generated during the heating process in the heating chamber can be transferred to the interior of the mandrel. Thus, when the heating chamber performs high-temperature curing on winding equipment A, a large amount of heat energy is generated, a portion of which exists in the form of "waste heat." The waste heat utilization system can collect this waste heat and transfer it to the interior of the mandrel of winding equipment B within the working chamber. In this way, during the winding process of winding equipment B, the wound fiberglass cloth can be preheated from inside the mandrel (i.e., preheating while winding), which can increase the initial temperature of the material. When winding equipment B completes winding and moves to the heating chamber, the fiberglass cloth on winding equipment B is already at a high temperature (preheated state). At this point, there is no need to start heating from room temperature, which can significantly shorten the heating time and the total curing cycle, improve product molding quality, increase the turnover rate of the heating chamber equipment, enhance system capacity, and also improve energy utilization efficiency.

[0017] In addition, the control system can separately heat the curing system, control the winding equipment and the waste heat utilization system, thereby enabling the entire molding device to operate automatically, which helps to improve the automation level of the equipment.

[0018] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

For example, see [link to relevant documentation]. Figure 1 "Inner" and "outer" refer to the inner and outer contours of the corresponding structures. Furthermore, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0024] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0025] like Figures 1 to 5 As shown, this disclosure provides a thermosetting fiberglass cloth winding and curing molding apparatus, including a housing 10, a winding device 20, a heating and curing system 30, a waste heat utilization system 40, and a control system. The housing 10 includes a main body 11 and a first movable door 12. The main body 11 has a cavity 13. The first movable door 12 is movably installed in the cavity 13 to separate a working chamber 131 and a heating chamber 132. The winding device 20 is movably disposed in the cavity 13 and has a first position located in the working chamber 131 and a second position located in the heating chamber 132. The winding device 20 includes a vehicle body 21 and a winding device 20. The core mold 22 is rotatably mounted on the vehicle body 21. The core mold 22 is used to wind the glass fiber cloth output from the output end of the resin impregnation system. The heat curing system 30 includes a temperature sensor 31 and a heater 32. The temperature sensor 31 is used to detect the temperature and humidity of the heating chamber 132. The heater 32 is used to heat the heating chamber 132. The input end of the waste heat utilization system 40 is connected to the heating chamber 132. The output end of the waste heat utilization system 40 is used to communicate with the interior of the core mold 22. The winding equipment 20, the heat curing system 30 and the waste heat utilization system 40 are electrically connected to the control system.

[0026] Temperature sensor 31 is used to monitor the temperature and humidity of heating room 132.

[0027] The heater 32 is used to heat the heating chamber 132 to complete the curing process of the fiberglass cloth.

[0028] The control system can communicate with the temperature sensor 31 and can control the heater 32 to adjust the temperature of the heating chamber 132 based on the data detected by the temperature sensor 31, so that the temperature in the heating chamber 132 is always in a suitable heating state.

[0029] Through the above technical solution, with the setting of workroom 131 and heating room 132, the winding equipment 20 can first wind the glass fiber cloth output from the resin impregnation system in workroom 131. After the winding is completed, the winding equipment 20 can move from workroom 131 to heating room 132 through the first movable door 12, and use the heating and curing system 30 in heating room 132 to heat and cure the glass fiber cloth on the mandrel 22. Meanwhile, workroom 131 can be used for the next winding equipment 20 to perform a new round of winding. In other words, the separation design of workroom 131 and heating room 132 allows the winding and curing processes to be carried out in parallel in two independent spaces. That is, when winding equipment 20 (A) is curing in heating room 132, winding equipment 20 (B) can perform a new winding operation in workroom 131. This alternating operation mode can realize continuous production, reduce equipment waiting time, and further improve equipment utilization and production efficiency.

[0030] Furthermore, through the waste heat utilization system 40, since the input end of the waste heat utilization system 40 is connected to the heating chamber 132 and the output end of the waste heat utilization system 40 is used to connect to the interior of the mandrel 22, the waste heat generated during the heating process in the heating chamber 132 can be transported to the interior of the mandrel 22. Thus, when the heating chamber 132 performs high-temperature curing on the winding equipment 20(A), a large amount of heat energy is generated, a portion of which exists in the form of "waste heat." The waste heat utilization system 40 can collect this waste heat and transport it to the interior of the mandrel 22 of the winding equipment 20(B) within the working chamber 131. In this way, during the winding process of the winding equipment 20(B), the wound fiberglass cloth can be preheated from inside the mandrel 22 of the winding equipment 20(B) (i.e., preheating while winding), which can increase the initial temperature of the material. When the winding equipment 20(B) completes winding and moves to the heating chamber 132, the fiberglass cloth on the winding equipment 20(B) is already at a high temperature (preheated state). At this point, there is no need to start heating from room temperature, which can significantly shorten the heating time and the total curing cycle, improve the product molding quality, increase the turnover rate of the heating room equipment, enhance system capacity, and also help improve energy utilization.

[0031] In addition, the control system can heat the curing system 30, control the winding equipment 20 and the waste heat utilization system 40 respectively, so that the entire molding device can operate automatically, which is conducive to improving the automation level of the equipment.

[0032] Optionally, the first movable door 12 can be a flexible door curtain, a lifting door structure, or a sliding door structure; this disclosure does not impose any limitations on this. When the first movable door 12 is a lifting door structure or a sliding door structure, it can be electrically connected to the control system.

[0033] As one implementation method, such as Figures 1 to 3 As shown, the waste heat utilization system 40 includes an exhaust fan 41 and an air outlet duct 42. The exhaust fan 41 is installed on the air outlet duct 42. A heater 32 is installed on the top wall of the heating chamber 132. An air outlet 1321 is installed on the side wall of the heating chamber 132 near its bottom wall. The inlet of the air outlet duct 42 is connected to the air outlet 1321, and the outlet of the air outlet duct 42 is connected to the interior of the core mold 22.

[0034] The exhaust fan 41 can transport the waste heat air through the exhaust duct 42 to the mandrel 22 of another winding device 20(B) located in the work room 131. The hot air flows inside the mandrel 22, and through convection heat transfer, it heats the mandrel 22 and the wound glass fiber cloth from the inside, which can achieve winding and preheating at the same time, and can increase the initial temperature of the material.

[0035] As one implementation method, such as Figures 1 to 3As shown, there are multiple heaters 32, including a first heater group and a second heater group arranged at intervals in a first direction. The heating chamber 132 has a central axis arranged along the length of the heating chamber 132. The first heater group and the second heater group are arranged symmetrically about the central axis in the first direction. The first heater group includes multiple heaters 32 arranged at intervals in a second direction. The second heater group includes multiple heaters 32 arranged at intervals in the second direction. The number of heaters 32 in the first heater group is equal to the number of heaters 32 in the second heater group and corresponds one-to-one. The first direction is perpendicular to the second direction, and the second direction is set to be the same as the extension direction of the central axis.

[0036] By dividing multiple heaters 32 into two symmetrically arranged groups, and arranging them equidistantly along the length of the heating chamber 132 within each group, a spatially symmetrical, uniformly distributed, and comprehensively covered heating system is constructed. This design not only improves the thermal uniformity and process stability of the heating chamber 132, but also enhances the system's controllability and adaptability.

[0037] As one implementation method, such as Figure 2 As shown, the heating room 132 includes an air outlet wall 1322, which is located on one side of the heating room 132. The air outlet wall 1322 has an air outlet cavity and is provided with multiple through holes communicating with the air outlet cavity. The multiple through holes are arranged at intervals along the second direction. An air outlet 1321 communicating with the air outlet cavity is provided on the outer wall of the air outlet wall 1322.

[0038] The air outlet cavity can act as an air collection chamber, which can be used to collect the hot air drawn from the heating chamber 132.

[0039] Multiple through holes are arranged at intervals along the length (i.e., the second direction) of the heating chamber 132. The function of the multiple through holes is to collect hot air from different positions in the heating chamber 132, which can ensure that the sampling points cover the entire heating section, thereby improving the uniformity and efficiency of waste heat recovery.

[0040] As one implementation method, such as Figures 4 to 5As shown, the winding device 20 includes a motor 23 and a transmission assembly 24. The vehicle body 21 includes a first sleeve 211, a second sleeve 212, an air inlet pipe 213, and an air outlet pipe 214. The first sleeve 211 and the second sleeve 212 are arranged opposite to each other. The first sleeve 211 has a first mounting cavity 2111. One end of the first mounting cavity 2111 is set as a first open end, and the other end of the first mounting cavity 2111 is set as a first closed end. An air inlet 2112 communicating with the first mounting cavity 2111 is formed on the first closed end. One end of the air inlet pipe 213 is connected to the air inlet 2112, and the other end of the air inlet pipe 213 is connected to the outlet of the air outlet pipe 42. The second sleeve 212 has a second... The second mounting cavity 2121 has one end configured as a second open end and the other end configured as a second closed end. An exhaust port 2122 communicating with the second mounting cavity 2121 is formed on the second closed end. An exhaust pipe 214 is connected to the exhaust port 2122. The core mold 22 is constructed as a hollow columnar structure. The two ends of the core mold 22 are rotatably connected to the first mounting cavity 2111 and the second mounting cavity 2121, respectively. The air inlet 2112 and the exhaust port 2122 can communicate with the interior of the core mold 22. The motor 23 is mounted on the outer wall of the first sleeve 211. The output shaft of the motor 23 is connected to the core mold 22 through the transmission assembly 24.

[0041] Specifically, the waste heat air from the heating chamber 132 enters the first mounting cavity 2111 of the first sleeve 211 via the air outlet duct 42 and the air inlet duct 213, and then enters the interior of the core mold 22 through the air inlet 2112. The air flowing out from the interior of the core mold 22 (whose temperature drops after heat exchange) is discharged through the exhaust port 2122 and the exhaust duct 214 of the second sleeve 212.

[0042] Through the exhaust duct 214, hot air releases heat within the mandrel 22, lowering its temperature. This allows the air to be exhausted into the working chamber 131 via the exhaust duct 214 at the other end of the mandrel 22. This raises the temperature of the working chamber 131, further insulating the wound fiberglass cloth from the outside of the mandrel 22 of the winding equipment 20(B), helping to maintain the temperature of the fiberglass cloth and prevent rapid heat loss. In other words, the low-temperature hot air (waste heat) that would otherwise be completely discharged can be reused, improving the energy recovery rate of the entire device and reducing energy costs. This design, through the dual effects of direct heating inside the mandrel 22 and indirect insulation in the working chamber 131, achieves comprehensive heating of the fiberglass cloth.

[0043] As one embodiment of the transmission component 24, such as Figures 4 to 5As shown, the transmission assembly 24 includes a transmission rod 241 and a rotating plate 242. The axial direction of the output shaft of the motor 23 is coaxial with the axial direction of the core mold 22. The rotating plate 242 is a hollow plate. The rotating plate 242 is located in the first mounting cavity 2111 and is rotatably connected to the first mounting cavity 2111. One end of the transmission rod 241 is connected to the rotating plate 242, and the other end of the transmission rod 241 extends out of the first sleeve 211 and is connected to the output shaft of the motor 23. One end of the core mold 22 is inserted into the first mounting cavity 2111 and connected to the side of the rotating plate 242 away from the transmission rod 241. The other end of the core mold 22 is inserted into the second mounting cavity 2121.

[0044] Specifically, after the motor 23 starts, its output shaft begins to rotate and transmits the rotation to the rotating plate 242 located in the first mounting cavity 2111 via the transmission rod 241. The rotating plate 242 rotates accordingly, causing one end of the mandrel 22 connected to it to rotate as well. Since the other end of the mandrel 22 can be stably supported by the second sleeve 212, the entire mandrel 22 can rotate smoothly. While the mandrel 22 is rotating, the glass fiber cloth output from the resin impregnation system can be wound onto the surface of the mandrel 22. By controlling the speed and direction of the motor 23, winding at different densities and angles can be achieved to meet various process requirements.

[0045] As one implementation method, such as Figures 4 to 5 As shown, the diameter of the air inlet 2112 is larger than the diameter of the air outlet 2122.

[0046] The air inlet 2112 has a large diameter, which allows more hot air to enter the core mold 22 at a higher flow rate, enabling the core mold 22 and the glass fiber cloth wrapped around it to heat up quickly and improve heating efficiency.

[0047] The exhaust vent 2122 has a small diameter, which limits the outflow speed of the air and allows the hot air to stay inside the core mold 22 for a longer time. This increases the chance of heat transfer to the material and thus improves energy utilization efficiency.

[0048] As one implementation method, such as Figures 1 to 5As shown, the air outlet duct 42 includes a first flexible hose 421 and a second flexible hose 422. The waste heat utilization system 40 also includes a support frame 43, a cylinder 44, and a telescopic rod 45. One end of the second flexible hose 422 is connected to the other end of the air inlet duct 213, and the other end of the second flexible hose 422 passes through the main body 11 and is connected to the output end of the exhaust fan 41. The input end of the exhaust fan 41 is connected to one end of the first flexible hose 421, and the other end of the first flexible hose 421 is connected to the air outlet 1321. The support frame 43 is installed on the top of the main body 11, and the cylinder 44 and the telescopic rod 45 are both mounted on the support frame 43. The telescopic rod 45 is vertically arranged, and its lower end passes through the main body 11 and is connected to the outer wall of the second hose 422. The cylinder 44 is connected to the telescopic rod 45 in a transmission manner. The cylinder 44 can drive the telescopic rod 45 to extend or shorten, so that the second hose 422 can switch between the working state and the closed state. In the working state, the telescopic rod 45 extends so that the end of the second hose 422 away from the first hose 421 is connected to the other end of the air inlet pipe 213. In the closed state, the telescopic rod 45 shortens so that the end of the second hose 422 away from the first hose 421 is disconnected from the other end of the air inlet pipe 213.

[0049] The control system can control the extension and retraction of the telescopic rod 45 via the cylinder 44 to automatically connect and disconnect the second hose 422 from the air inlet pipe 213, thus constructing an intelligent, safe, and reliable automatic docking system for waste heat transfer. Specifically, after the winding equipment 20(B) enters the workroom 131 and is positioned, the control system controls the cylinder 44 to drive the telescopic rod 45 to extend, causing the second hose 422 to move downwards, so that its end automatically docks with the air inlet pipe 213, and begins to use the exhaust fan 41 and exhaust pipe 214 to transfer waste heat for preheating. At this time, the second hose 422 is in working condition.

[0050] When the second hose 422 is closed, when the winding operation is completed or the winding equipment 20 needs to be moved into the heating room 132, the control system controls the cylinder 44 to retract the telescopic rod 45, thereby disconnecting the second hose 422 from the air inlet pipe 213 to avoid obstructing the movement of the winding equipment 20 or causing damage to the pipe. Simultaneously, the exhaust fan 41 is turned off. At this time, the second hose 422 is in the closed state.

[0051] As one implementation method, such as Figures 4 to 5As shown, the winding device 20 also includes a controller. The air inlet pipe 213 has an L-shaped structure, including a first pipe body 2131 and a second pipe body 2132. The air outlet pipe 42 also includes a connecting part 423 and a magnetic part 424. The end of the first pipe body 2131 away from the second pipe body 2132 is connected to the air inlet 2112. An electromagnet part 2133 is provided on the outer wall of the end of the second pipe body 2132 away from the first pipe body 2131. The electromagnet part 2133 is a first annular protrusion extending circumferentially along the second pipe body 2132. The top surface of the electromagnet part 2133 is flush with the end of the second pipe body 2132 away from the first pipe body 2131. The motor 23 is electrically connected to the electromagnet part 2133 via a controller. A magnetic part 424 is provided on the outer wall of the end of the second flexible tube 422 away from the first flexible tube 421. The magnetic part 424 is a second annular protrusion extending circumferentially along the second flexible tube 422. The magnetic part 424 can attract the electromagnet part 2133. The bottom surface of the magnetic part 424 is flush with the end of the second flexible tube 422 away from the first flexible tube 421. The second flexible tube 422 is constructed as a corrugated tube. A connecting part 423 is formed on the outer wall of the end of the second flexible tube 422 away from the first flexible tube 421. The lower end of the telescopic rod 45 is connected to the connecting part 423.

[0052] The automatic docking process of the second hose 422 and the air inlet pipe 213 can be as follows: when the winding equipment 20 moves to the predetermined position (preheating station), the position sensor (e.g., photoelectric switch or proximity switch) on the work area 131 detects that the winding equipment 20 is correctly positioned and sends a "in position" signal to the controller.

[0053] After receiving the "in position" signal, the controller first activates cylinder 44, causing telescopic rod 45 to extend downwards. The second hose 422, fixed to the lower end of telescopic rod 45, moves downwards and gradually approaches the end of the second pipe body 2132 of the L-shaped air inlet duct 213. At this time, the corrugated structure allows the second hose 422 to bend freely and adjust its angle within a certain range to compensate for any minor positional deviations.

[0054] When the second hose 422 approaches the designated distance, the controller (not shown) supplies power to the electromagnet 2133. The electromagnet 2133 can generate a magnetic field to attract the magnetic part 424 on the second hose 422. The magnetic part 424 and the electromagnet 2133 are tightly magnetically attracted, so that a stable and reliable connection can be formed between the second hose 422 and the air inlet pipe 213.

[0055] Once it is confirmed that the electromagnet part 2133 and the magnetic part 424 are successfully attracted, the control system starts the exhaust fan 41. The exhaust fan 41 draws the residual hot air from the heating chamber 132 through the first hose 421 and then delivers it to the core mold 22 inside the working chamber 131 through the second hose 422. After the hot air enters the core mold 22, it preheats the fiberglass cloth on the core mold 22.

[0056] After preheating is complete, the control system issues a command to shut down the exhaust fan 41. Once the air supply stops, the controller cuts off the power to the electromagnet 2133, causing it to lose its magnetism. At this point, the attraction between the electromagnet 2133 and the magnetic part 424 disappears, preparing for the next separation step. After confirming that all operations are complete and safety conditions are met, the system prepares to initiate the automatic disconnection of the second hose 422 and the air inlet pipe 213.

[0057] The automatic disconnection process between the second hose 422 and the air inlet pipe 213 can be described as follows: The controller reactivates the cylinder 44, causing the telescopic rod 45 to slowly retract. The second hose 422 moves upward with the telescopic rod 45, separating from the air inlet pipe 213 (the end of the second tube body 2132 of the L-shaped air inlet pipe 213). During the separation process, since the adsorption force has disappeared, no additional resistance is generated, ensuring a smooth separation. Finally, the second hose 422 is completely detached from the air inlet pipe 213, and the winding equipment 20 can continue to the next process (i.e., the heat curing work).

[0058] The entire automated docking process, through precise position control, intelligent electromagnetic adsorption mechanisms, efficient airflow management, and reliable separation operations, achieves full automation from equipment positioning to waste heat transfer and safe disconnection. This design not only improves production efficiency and reduces manual intervention but also ensures high precision and excellent sealing for each docking, greatly enhancing the system's reliability and safety.

The bottom of the first support leg 2151 and the second support leg 2161 are both provided with a traveling wheel 217. The guide rail assembly is installed at the bottom of the cavity 13 and includes two guide rails 60. The two guide rails 60 are arranged at intervals along the first direction.

[0061] The winding device 20 can slide with the guide rail 60 through the traveling wheels 217 on the vehicle body 21 to ensure that the vehicle body 21 moves smoothly and does not deviate.

[0062] The second position sensor 51 is used to detect whether the winding equipment 20 has fully entered the curing station of the heating chamber 132.

[0063] The second movable door 14 is used to allow the winding equipment 20 to enter the work room 131.

[0064] The third movable door 15 is used to allow the winding equipment 20, which has been heated and cured, to be moved out of the heating chamber 132 so as to facilitate the next demolding process.

[0065] The working window 1311 allows the glass fiber cloth output from the resin impregnation system to pass through and be wound onto the mandrel 22 to achieve continuous feeding.

[0066] Among them, the observation window 1323 allows staff to observe the curing status or conduct inspections in the heating chamber 132 in real time.
